Guidance of ransomware measures

Data are dangerous now! Please be careful. Data of company are aimed at! We cannot read data and do, and malware, ransomwares requiring ransom money are popular!Data are dangerous now! Please be careful. Data of company are aimed at! We cannot read data and do, and malware, ransomwares requiring ransom money are popular!

With ransomware

  • Client PC infected with virus is malware encrypting accessible file. We encrypt data saved in NAS without permission and cannot read and, as well as data in PC, do.
  • Ransom money (money) is required to return to state that can read data. There is no guarantee that data can read even if we pay ransom money.
  • Example that aimed at old NAS where PC and backup measures that Security Update is not made are not done is reported.

However, there is no guarantee that can restore data when we pay ransom money!

What kind of measures should we take?

For coding by having been infected with ransomware, we recommend backup of NAS data! Storage, generation control of a fixed period of time of duties data and email are to have you back up and can minimize damage of ransomware just in case.

Figure of measuresFigure of measures

It is backed up data regularly!
For unexpected situation, we recommend backup of data.
We are more reliable by not sharing HDD of backup of NAS!
We can take measures not to encounter damage to file in Network joint ownership.

In the case of Windows NAS series of ELECOM

It inflects with volume shadow copy of Windows NAS!

State just before ransomware infection can restore data!

Windows NAS figure 1Windows NAS figure 1

  • We use Windows NAS as file server and recommend utilization by volume shadow copy (VSS) function of NAS.
  • We can let data which write current data in ransomware, and were saved in kan eratatoshitemo, VSS area just before that restore to the original state and minimize loss by any chance.

We prevent infection of ransomware in Windows NAS!

We thoroughly prevent ransomware by double virus measures!

It has been checked the operation of representative virus measures software

  • Virusbuster corporate edition 11

  • As Windows Storage Server deployment NAS of ELECOM can install virus measures software in the NAS body, we can remove file which infected ransomware well
  • In addition to virus measures to client PC, the NAS body can protect data important more strongly by making virus measures.
Recommended model

In the case of Linux NAS series of ELECOM

Environmental construction that is more reliable by history differential backup!

Figure of backup

  • Data takeoff before we are encrypted by backing up history difference share is possibility. We minimize damage.

We are backed up by external USB HDD

For further long-windedness, we are backed up by external USB HDD

Windows NAS of ELECOM can back up data on NAS using USB HDD for backup.
In what we set to refuse access from client PC, we can prevent data from being infected with virus directly.
